SAMPLE
The <SAMPLE> key is used to set the current sample position. This
has to be done before a sample series is run.
At the start of a method this position is assumed to be the first sample
in a series. If no sample position has been set then the Sample Proc-
essor will select rack position 1.

MOVE
With <MOVE> a vessel or a particular rack position can be moved to
the active tower or a robotic arm can be swung to an external position.
As well as the actual sample beaker a maximum of 16 possible spe-
cial beakers can also be defined. A particular rack position can be
moved to directly by entering the position number (with the numerical
keys).
The direction and speed of rotation can be altered in the parameter
menu.
